如何使Robot按住鼠标键一定时间？

只需在两个动作之间睡眠一下（以毫秒为单位）：

1. Thread.sleep(long millis);

        robot.mousePress(InputEvent.BUTTON1_MASK);    try { Thread.sleep(1000); } catch(Exception e) {} // Click one second    robot.mouseRelease(InputEvent.BUTTON1_MASK);

1. Robot.delay(long millis);

        robot.mousePress(InputEvent.BUTTON1_MASK);    robot.delay(1000); // Click one second    robot.mouseRelease(InputEvent.BUTTON1_MASK);
